Communication Mode
In the 78K0/KE1+, a communication mode is selected by inputting pulses (up to 11 pulses) to the FLMD0 pin after
The following table shows the relationship between the number of pulses and communication modes.
2. The possible setting range differs depending on the voltage. For details, refer to the chapters of electrical
